Doctor Man manages to launch a neo-mechagigan named Satan Megas in order to test its power by fighting the Bio Robo. Despite the robot's efforts to destroy the mecha twice and to the Biomen's horrible shock, Satan Megas appears immortal and is mostly revived by a junior high school girl who had her eyes glowing in red when it was incapacitated or obliterated. Doctor Man was impressed to see his mecha-human creation is able to restore he mecha back to life from her control even the Big Three wasn't impressed by it.

Shuichi takes her to the mysterious professor named Professor Shibata which is his mentor and seeing the girl was made by someone he knew. He tells Shuichi to leave so that he can fix the girl up. Professor Shibata does his best to fix it and he manages to place a device so that she can have her conscious state and can communicate with others freely.
When the Biomen continues to find her, they are unaware that the girl is with Shuichi as he orders Shingo to examine the girl which he briefly transforms to Green2 to use Super Electronic Scope and revealing that the girl is a mechaclone but they are unaware that they are been watched by Professor Shibata. As the group proceeds to get her, they are stopped by Professor Shibata and he explains to them that the girl will be fine as he put the device known as the conscious circuit so that she is will be good person and no longer in Doctor Man's clutches while both the girl and Shuichi are together they are observed by Mason in his human disguise to inform Doctor Man about this.
